FABRIC.

Application filed 0mm 17, 1922. Serial No. 595,142.

To all whom it mag convent:

Be it known that I, Faun B. ,MANLEY, a citizen of the United States, residing at Paterson in the county of Passaic and State of New jersey, have invented certain new and useful Improvements in Fabrics, of which the following is a specification.

My present invention re ates to a fabric particularly adapted for use in belting. In the production of. such belting, the fabric is coated with rubber or similar compound and a number of layers combined together. In such a belting, the warp threads should be as nearly inextensible as possible, because substantially the. only strain on the belt is longitudinally, thereof. On the other hand,

, since such belts are at times turned over small pulleys, the belt should be capable of bending crosswise-of these warp strands rather easily, .while, in order that the belt shall have lateral stiffness, the resistance to bending parallel to. the warp strands should be comparatively great. When the fabric is used for belting, it should also-be of such a character that belt hooks may be inserted in the belt --to fasten the ends thereof together without danger of pulling out of the fabric The novelfabric described herein has all of the foregoing qualities, and in addition, is of such a character that the rubber coating may be applied thereto, so as to be substantially locked to the surface of the fabric in the direction in which such rubber is liable to be pulled when the fabric is used in belting.

Fig. 1 is a plan view of an illustrative form of my novel fabric.

. Fig. 2 is a cross section on the line 22 of Fig. 1.

Fig.3 is a cross section on, the line 3-3 of Fig. 1.

For purposes of illustration, I have shown an embodiment of my invention particularly adapted for use in belting, in which the cord or yarn warp strands 10, preferably in the form of inextensible cords having but little stretch, are located .side by side without intervening space between adjacent cords. These cords extend in straight, parallel lines throughout the length of the fab I the cord strands 10 on either side thereof,

the weft strands being relatively widely spaced apart.- Such we'ft strands extend across the warp substantially without un dulations.

Preferably between each pair of warp strands 10, there is a binder strand 12 which passes alternately over the weft strands 11 on' opposite sides of the warp 10, these binder strands preferably being. of relatively small diameter and exerting enough pressure on the weft strands 11 to hold these latter and the cord strands 10 in position in the fabric, but without drawing the weft strands 11 down between the cord strands 10.

When the fabric so far described is used inbelting, the fabric is coatedwith rubber or other composition in the usual manner, and then several plies are pressed together, with the cords 10 running lengthwise of the belt. -When the belt is subjected to longi tudinal pull in use, such pull will cause a longitudinal extension of the belt only by the amount of the elasticity of the cord strands 10 themselves. Since these strands lie in straight lines in the fabric, there will be no stretching of the belt due to the straightening out of undulations in the cords.

When the fabric is used for belting, I prefer to proportion the diameters of the weft strands 11 and their relative spacing along the cord strands 10, .so that, while there will be sufi'cient space between these weft strands to permit the composition to pass between them down to the surfaces of 'I the cord strands 10, nevertheless the weft strands will present suflicient resistance to bending crosswise of the fabric (i. e., parallel with the cord strands 10), so that the belt will be much stiffer crosswise than it is lengthwise. will produce a belt sum of the resistance to bending of all of the individual weft strands. -When the fabric is bent crosswise of the weft strands 11, such bending is resisted not only by the strands themselves, but also by the binder strands 12, because by such bending, the weft strands on the out side of the bend tend to be elongated small size between adjacent cords. for, in--- terlocking the filler strands and serving to in the same maintain the cord warps and filler strands in position. i 4. A woven belt fabric having straight filler strands, relatively inextensible cord warps in close contact and free of undulations for carrying the load, and binder strands of relatively small size for interlocking-the straight filler strands free of undulations'to the cord war s.

5. A hose and belting duo comprising a plurality of primary warp ends in close relation and in rigid contact throughout their length, a plurality of filling threads spaced from each other upon opposite sides of, the warp ends, and secondary warp ends of relatively small size for tying the filling ends to the warp ends, the filling ends forming spaced ribs upon opposite sldes of the rigidly bound primary warp ends and dis osed transversely of and in protective re ation with said warp ends, said ribs on one side of the sheet of the warp ends being in staggered relation with the ribs on the other side of said sheet.

6. A hose and beltingl duck comprising rimary warp ends para el with each other 4 lane and laid in close contact each with the adjacent ends throughout their length to form a solid sheet, spaced filling threads located upon one side of the said sheet and extendin at a right angle to warp en s, a second set of threads located upon the oppoe solid sheet from the first said the primary spaced fillin site side of t relation thereto, that is to say with the spaces of one set of filling threads alternating with those of the other set, and secondary warp ends of relativel small diameter interlocking with and nding the spaced filling. threads to the solid sheet of primary warp ends all substantially as described'whe-reby is produced a duck wherein the constituent parts are in intimate relation and free of interstices or spaces between the adjacent parts.

7. A hose and belting duck comprising a plurality of rimary warp ends laid in close contact t roughout their length to form a solid sheet, a plurality of s aced filling threads located in staggered re ation upon opposite sides of the sheet, and secondary warp ends of relatively smallsize interlocked with the alternate fillin threads, said filling threads forming ribs raised above the surface of the solid sheet of primary warp ends and in protective'relation thereto.
